Encapsulation is the best method to protect the plant extracts against volatility and instability in the presence of air, light, moisture and high temperatures. Nevertheless, application of encapsulated plant extracts on the textiles requires a low-temperature and high rate processing to avoid from breaking or destroying of capsules. The present paper represents application of nanocapsules prepared by ultrasound irradiation assisted W/O/W microemulsion method on the cotton fabric through UV curing method. The surface and structure of nanocapsules and treated cotton fabric using FESEM and FT-IR indicated the spherical nanocapsules with size of 60–80nm stabilized on the fabric surface in a film layer feature. Also, the treated cotton fabric showed a good release behavior of 96h, a high stability against washing and rubbing tests and a relative good antimicrobial activity with 91, 89 and 94% reduction against S. aureus, E. coli and C. albicans, respectively.
